where \(<>\)  is averaging over the Fermi surface, \(<\Omega ^2>=1\) , \(t=T/T_c\) , \(\zeta (3)\simeq 1.2020\)  is Riemann's zeta function, \(\gamma \simeq 0.577\)  is the Euler constant [1]}. Because \(\Psi (T)\)  is obtained from the normalized \(\Omega \) , we only consider the ratio of \(c_1, c_2\) , and \(c_3\) .
